This may have  been covered, but I have found no answers.  I just got the drone 4, which I have flown 2 times, but when I try and fly it, it won't connect to my Ipad. Not sure what I should power on first, controller, or drone. I click on the calibrate button, but nothing happens.  I don't know how I was able to fly before, I have even tried re-booting everthing with no success.

Start RC. Next start airplane (Phantom 4). Then connect and start DJI GO.

Yes. And my suggestion is that Luzwick could try different lightning cables.
